The rivals have always been 200 TW, however they updated the compound. The rival S is geared toward autocross, and is supposed to come up to temp faster. They will still be producing the original rival compound for those who don't desire the qualities of the S. That's about all the info I've found on these tires.
OK, Thanks, I figured it was something like that since so many were running the older Rivals at the Optima Ultimate Street car challenge last year, and they require at least a 200 tread wear, correct?
